The hardware automatically zero pads incomplete block ciphers blocks without raising any errors. This is a screw-up. This was noticed by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS tests that sent a incomplete blocks and expect them to fail. This fixes: cbc-aes-ppc4xx encryption unexpectedly succeeded on test vector "random: len=2409 klen=32"; expected_error=-22, cfg="random: may_sleep use_digest src_divs=[96.90%@+2295, 2.34%@+4066, 0.32%@alignmask+12, 0.34%@+4087, 0.9%@alignmask+1787, 0.1%@+3767] iv_offset=6" ecb-aes-ppc4xx encryption unexpectedly succeeded on test vector "random: len=1011 klen=32"; expected_error=-22, cfg="random: may_sleep use_digest src_divs=[100.0%@alignmask+20] dst_divs=[3.12%@+3001, 96.88%@+4070]" Cc: Eric Biggers <ebiggers@kernel.org> Cc: stable@vger.kernel.org [4.19, 5.0 and 5.1] Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
